Description

Technical Field

[0001] This utility model relates to a sorting device for sorting packages (such as express delivery packages), and belongs to the field of logistics sorting technology. Background Technology

[0002] Parcel sorting equipment is essential for modern logistics to reduce labor intensity and improve sorting efficiency. For example, patent document CN207941724U discloses a parcel sorting device that includes an identification device and a sorting device. The identification device includes a support, a scanning device, a conveyor belt, and a weighing structure. The scanning device and weighing structure are fixedly installed on the support, and the conveyor belt is installed on the weighing structure. The scanning device faces the conveyor belt. The sorting device includes a machine tool and a moving structure. The moving structure is slidably installed on the machine tool and moves back and forth on it. The machine tool is located in the extension direction of the conveyor belt and moves the parcels from the conveyor belt to the moving structure for sorting. The weighing structure weighs the parcels during transport, and the scanning device scans the information on the parcels. The sorting device sorts the parcels to the corresponding workstations based on the scanned information. This sorting device requires no manual labor, achieving full automation and reducing errors. However, when faced with large-scale sorting demands, the sorting efficiency of this equipment becomes insufficient. To improve sorting efficiency, it is necessary to purchase more sorting equipment. Furthermore, when faced with a wide variety of sorting needs, numerous corresponding sorting ports are required. However, the sorting ports of the aforementioned sorting equipment are limited and cannot meet the sorting demands, necessitating the addition of more sorting equipment. The immediate problem with purchasing more sorting equipment is that it occupies a large amount of workshop space and requires more personnel to control it. Utility Model Content

[0003] The purpose of this invention is to provide a three-dimensional parcel sorting device to improve the efficiency of parcel sorting.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] The three-dimensional parcel sorting device includes a second conveyor line that moves up and down under the drive of a lifting device. Downstream of the second conveyor line are multiple sorting racks, each with a third conveyor line. On each sorting rack, the third conveyor line moves horizontally on the rack under the drive of a horizontal moving device. When the second conveyor line moves to a sorting rack (corresponding to parcel information) under the drive of the lifting device, the parcels on the second conveyor line are conveyed to the third conveyor line on that rack. The third conveyor line moves to the sorting position (i.e., the sorting port) on the rack under the drive of the horizontal moving device, and then conveys the parcels on it to the sorting position.

[0006] The lifting device can be implemented using an existing technology. Specifically, in this utility model, the lifting device includes a vertical guide rail, on which a vertical slider is mounted. The vertical slider moves up and down on the vertical guide rail and is connected to a second conveyor line. The second conveyor line moves along the vertical guide rail under the drive of a vertical power device. The vertical power device includes a vertical motor, a vertical drive wheel driven by the vertical motor, a vertical driven wheel, and a vertical belt on the vertical drive wheel and the vertical driven wheel. The vertical belt is connected to the second conveyor line.

[0007] The horizontal moving device can be implemented using one of the existing technologies. Specifically, in this utility model, the horizontal moving device includes a horizontal guide rail, on which a horizontal slider is disposed. The horizontal slider moves horizontally on the horizontal guide rail and is connected to the third conveyor line. The third conveyor line moves along the horizontal guide rail under the drive of a horizontal power device. As another implementation, the horizontal moving device includes a horizontal guide groove, within which a guide wheel is disposed. The guide wheel moves horizontally within the horizontal guide groove and is connected to the third conveyor line. The third conveyor line moves along the horizontal guide groove under the drive of a horizontal power device. The horizontal power device includes a horizontal motor, a horizontal driving wheel driven by the horizontal motor, a horizontal driven wheel, and a horizontal belt on the horizontal driving wheel and the horizontal driven wheel. The horizontal belt is connected to the third conveyor line.

[0008] To improve sorting efficiency, there are two second conveyor lines. A first conveyor line is installed upstream of the second conveyor line to facilitate package transport. A transition conveyor line is installed between the first and second conveyor lines to match their speeds and buffer the processing of the second conveyor line.

[0009] The first conveyor line is equipped with an identification device (such as common camera image recognition, QR code recognition, etc.) for identifying package information. The first conveyor line transports the package to the second conveyor line. Based on the identified package information, the second conveyor line moves vertically and assigns the package to a sorting rack (layer) corresponding to the identified information. On this sorting rack, the third conveyor line moves to the sorting port corresponding to the identified information. Finally, the third conveyor line transports the package to the sorting port.

[0010] Specifically, the first conveyor line, the transition conveyor line, the second conveyor line, and the third conveyor line are all powered conveyor belts. Common powered conveyor belts are those with electric rollers as the power rollers, or those with motor-driven power rollers.

[0011] To prevent packages on the third conveyor line from detaching during movement (horizontal movement on the sorting rack), side plates are provided on both sides of the third conveyor line. Upstream and downstream of the third conveyor line, movable baffles are installed between the two side plates, and these movable baffles are mounted on the side plates via rotating shafts. The side plates and baffles enclose the third conveyor line. The rotating shaft is connected to a motor, which drives the shaft to rotate, thus opening and closing the baffles.

[0012] The sorting device of this utility model has a three-dimensional multi-layer sorting rack with high space utilization. Under the condition of occupying the same workshop area, on the one hand, the sorting openings are multiplied (the specific multiplier depends on the number of layers), and the sorting types on the same equipment are multiplied. On the other hand, a sorting device has a multi-layer sorting rack through the connection of a second conveyor line, which improves sorting efficiency. Attached Figure Description

[0020] Figure 7 This is a schematic diagram of the third conveyor line. Detailed Implementation

[0021] like Figure 1-7 As shown, the three-dimensional parcel sorting device includes:

[0022] - First conveyor line 1. (e.g.) Figure 1 , 2As shown, the first conveyor line 1 consists of two lines (to improve sorting efficiency), distributed left and right. Both are powered conveyor belts (such as commonly used electric rollers or motor-driven rollers, hereinafter the same), installed on the chassis, and serve as the package supply section (i.e., providing packages) for the entire sorting device. Packages to be sorted are conveyed from here to the sorting section. An identification device (such as common camera image recognition, QR code recognition, etc.) for identifying package information is installed at the first conveyor line 1 (as shown above). The identification device is installed inside the upper mounting cover 102. Of course, package information identification is not limited to this; it can also be achieved using existing identification methods such as barcode scanners.

[0023] - Transition conveyor line 2. (e.g., ...) Figure 3 As shown, there are two transition conveyor lines 2, distributed left and right, both of which are powered conveyor belts, located between the first conveyor line 1 and the second conveyor line 3, as follows. Figure 3 The section shown, mounted on the support, is the package supply section. This section serves as a buffer because the first conveyor line 1 only transports packages, while the second conveyor line 3 needs to vertically "find" a specific sorting rack 5 before transporting it. This results in a speed mismatch between the first and second conveyor lines 1 and 3. To match the speeds of the first and second conveyor lines 1 and 3, and to buffer the processing of the second conveyor line 3, a transition conveyor line 2 is provided between the first and second conveyor lines 1 and 3. A package identification device can also be installed here.

[0024] -Second conveyor line 3. (e.g., ...) Figure 3 , 4 As shown in Figure 5, there are two second conveyor lines 3, distributed left and right, both of which are powered conveyor belts. The second conveyor lines 3 also serve as the package supply section. On one side (left), the first conveyor line 1, transition conveyor line 2, and second conveyor line 3 correspond to each other, and on the other side (right), the first conveyor line 1, transition conveyor line 2, and second conveyor line 3 correspond to each other. For example... Figure 4As shown, the second conveyor line 3 is installed on a lifting device and moves up and down under the drive of the lifting device. Based on the package information, it moves to the sorting rack 5 corresponding to the package information. One embodiment of the lifting device (not limited to this) includes a vertical guide rail with a vertical slider on it. The vertical slider moves up and down on the vertical guide rail and is connected to the second conveyor line 3 via a connector. The second conveyor line 3 moves along the vertical guide rail under the drive of a vertical power device. Another embodiment of the lifting device (not limited to this) includes a vertical guide groove 301 with guide wheels 306 (guide wheels in different directions can be provided for stability). The guide wheels 306 move horizontally within the vertical guide groove 301 and are connected to the third conveyor line 4. The third conveyor line 4 moves along the vertical guide groove 301 under the drive of a vertical power device. One embodiment of the vertical power device (not limited to this) includes a vertical motor, a vertical drive wheel 302 driven by the vertical motor, a vertical driven wheel 303, and a vertical belt 304 on the vertical drive wheel 302 and the vertical driven wheel 303. The vertical belt 304 is connected to the second conveyor line 3 through a connector 305.

[0025] -Third conveyor line 4. (e.g.) Figure 6 , 7 As shown, a multi-layer sorting rack 5 is provided downstream of the second conveyor line 3, such as... Figure 6 The four layers are connected by supports and side plates on both sides, distributed vertically. Each layer of the sorting rack 5 is equipped with a third conveyor line 4, which is a sorting section. On each layer of the sorting rack 5, the third conveyor line 4 moves horizontally on the sorting rack 5 under the drive of a horizontal moving device. The third conveyor line 4 moves to the sorting position and conveys the packages on it to the sorting position (i.e., the sorting port). One embodiment of the horizontal moving device (not limited to this) includes a horizontal guide rail, on which a horizontal slider is provided. The horizontal slider moves horizontally on the horizontal guide rail and is connected to the third conveyor line 4. The third conveyor line 4 moves along the horizontal guide rail under the drive of a horizontal power device. Another embodiment of the horizontal moving device (not limited to this) has a structure similar to... Figure 5The structure is identical, including a horizontal guide groove, within which a guide wheel is installed. The guide wheel moves horizontally within the horizontal guide groove and is connected to the third conveyor line 4. The third conveyor line 4 moves along the horizontal guide groove under the drive of a horizontal power device. One embodiment of the horizontal power device (not limited to this) includes a horizontal motor, a horizontal drive wheel driven by the horizontal motor, a horizontal driven wheel, and a horizontal belt on the horizontal drive wheel and the horizontal driven wheel. The horizontal belt is connected to the third conveyor line 4. Since the third conveyor line 4 needs to move quickly horizontally on the sorting rack, side plates 402 and 403 are provided on both sides of the third conveyor line 4 to prevent packages from falling off during horizontal movement. Simultaneously, movable baffles 405 and 407 are provided between the two side plates 402 and 403 upstream and downstream of the third conveyor line 4. The movable baffles 405 and 407 are respectively mounted on the side plates 402 and 403 via rotating shafts 404 and 406 to prevent packages from falling off the third conveyor line 4 in the conveying direction. The rotating shafts 404 and 406 are connected to the motor. When the second conveyor line 3 conveys packages to the third conveyor line 4, the rotating shaft 404 of the movable baffle 405 upstream of the third conveyor line 4 rotates under the drive of the motor, and the movable baffle 405 is lifted, allowing packages to be conveyed from the second conveyor line 3 to the third conveyor line 4. At this time, the movable baffle 407 downstream of the third conveyor line 4 does not move, thus preventing packages from falling off the third conveyor line 4. When the third conveyor line 4 conveys packages to the sorting port, the rotating shaft 406 of the movable baffle 407 downstream of the third conveyor line 4 rotates under the drive of the motor, and the movable baffle 407 is lifted, allowing packages to be conveyed from the third conveyor line 4 to the sorting port. At this time, the movable baffle 405 upstream of the third conveyor line 4 does not move. The working principle is the same when packages on the third conveyor line 4 are conveyed to the sorting port in another direction.

[0026] During operation, taking a package as an example, the package is placed on the first conveyor line 1 by manual labor or a robotic arm, and an identification device is located above the first conveyor line 1. Figure 1 , 2 (Not shown in the diagram) The information on the package is identified (of course, the identification device can also be set above the transition conveyor line 2 and the second conveyor line 3). The first conveyor line 1 transports the package to the second conveyor line 3. Based on the identified package information, the second conveyor line 3 moves up and down under the drive of the lifting device. The second conveyor line 3 moves up or down to a sorting rack 5 corresponding to the package information. The second conveyor line 4 transports the package on it to the third conveyor line 4 of this sorting rack 5. The third conveyor line 4 moves on the sorting rack 5 to the sorting port corresponding to the package information. Finally, the third conveyor line 4 transports the package to the sorting port, realizing the sorting of the package.

[0027] In order to detect whether there are packages on the first conveyor line 1, the transition conveyor line 2, the second conveyor line 3, and the third conveyor line 4, and whether the packages are being conveyed, sensors can be installed on one or both sides of the first conveyor line 1, the transition conveyor line 2, the second conveyor line 3, and the third conveyor line 4, such as photoelectric sensors 101, 201, and 401 for detection.

[0028] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
